Teenagers who are deaf have better reading skills if their deafness was identified by the time they were nine months old.
Researchers have been studying the development of a group of children with permanent childhood hearing impairment (PCHI) at a very early age in a pilot screening program conducted in Southampton and London in the 1990s

Follow-up assessments when the children were eight years old showed those who were screened at birth had better language skills than those children who were not screened.
The new study, published in Archives of Disease in Childhood, further shows that longer term benefits of early detection also are evident when the children were 17.
When the teenagers’ level of reading development was compared to deaf teenagers who were not screened as newborn babies, the gap between the early and late confirmed groups had doubled between the two assessments.
Screen all babies?
“Our previous work has shown that children exposed to newborn hearing screening had, on average, better language and reading abilities at age eight years,” says Colin Kennedy, professor of neurology and pediatrics at University of Southampton. “We are now able to show that this screening program can benefit these children into their teenage years.
“We believe that the early superiority in the reading skills of the children who were screened may have enabled them to read more demanding material more frequently than their peers with later confirmed hearing difficulties, thus increasing the skill gap between the two groups.
“Screening all babies for hearing impairment at birth enables families to have the information they need to support their baby’s development, leads to benefits of practical importance at primary school and now, secondary school and further education.”
The researchers say the new results support the case for national governments to fund universal newborn hearing screening programs that increase the rates of early confirmation of hearing difficulties in the many developed and developing countries where screening programs for deafness are currently under discussion, but not yet adopted as national policy.
